Book excerpt: Orcinus Orca is the world's largest predator, and simultaneously a significant tourist asset and cultural icon for much of the Pacific Northwest. In the past two decades, the Southern Resident Killer whales (SRKW) have declined by more than 25 percent, and this population appears on a slow-motion path towards extinction. This paper combines elements from biology and economics to put forward a new methodology for investigating their collapse and presents empirical work supporting its novel explanation - the Orca Conjecture. The key mechanism is ecological - Gause's law of competitive exclusion - combined with a shock coming from booming trade with Asia. Using three different empirical methods drawn from economics, I find the attendant noise disturbance from increased ship traffic post-1998 has lowered births and raised deaths significantly, placing the SRKW on a slow-motion path towards extinction.

Available in PDF, EPUB and Kindle. Book excerpt: Orcinus Orca is the world's largest predator, and simultaneously a significant tourist asset and cultural icon for much of the Pacific Northwest. In the past two decades, the Southern Resident Killer whale (SRKW) population has declined by more than 25 percent, putting them at risk of extinction. The cause of this decline is hotly debated. This paper employs novel data, an innovative noise pollution model, and quasi-experimental methods borrowed from environmental economics to solve this puzzle. We find consistent evidence that vessel noise pollution from international shipping has lowered fertility and raised the mortality of the SRKW significantly. Had noise pollution remained at its pre-1998 levels, the SRKW population would be 30% larger. Noise pollution is a growing threat to marine mammals worldwide.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation concerns the southern resident killer whales (Orcinus orca), a genetically isolated population of fish-eating killer whales that frequent the international waters of the Salish Sea between the United States and Canada in the eastern Pacific Ocean. Research was conducted from June 1 to October 31, 2007 and from June 7 to October 31, 2008, between geographic coordinates: 48°12' to 49° N latitude by 122°43' to 123°50° W longitude. The southern resident killer whale population has experienced multiple fluctuations since population surveys were initiated by the Center for Whale Research (CWR) in the mid 1970's. In November 2005, the U.S. National Oceanic and Atmospheric Administration's National Marine Fisheries Service (NMFS), Northwest Regional Office listed the southern resident killer whales as an endangered distinct population segment of the species Orcinus orca under the United States Endangered Species Act (ESA). Several risk factors including reductions in the quantity and quality of prey (salmon), exposure to persistent toxins, and disturbance from vessel presence and associated noise were identified as contributing to the decline of this already small population. With the listing under the ESA, critical habitat was designated in the inland waters around the U.S. San Juan Islands, Washington State and the Canadian Gulf Islands, British Columbia, Canada. Chapter one, Managing Vessel-based Killer Whale Watching: A Critical Assessment of the Evolution from Voluntary Guidelines to Regulations in the Salish Sea, provides background on the southern resident killer whales and the robust international whale watching industry in the region. This chapter also provides a detailed history of local, state, federal and international vessel laws and guidelines for watching whales in the Salish Sea. Chapter two, Non-invasive methods to study southern resident killer whales and vessel compliance with regulations, describes a novel equipment package, consisting of a differential GPS integrated with a digital compass and laser rangefinder that allowed me to collect accurate geo-referenced locations and behavioral data on whales and vessels throughout the whale's critical habitat. To improve both the spatial and temporal data on whale-vessel interactions, the information collected with this equipment was used to assess vessel compliance with local, state and federal laws and the regionally accepted best-practices Be Whale Wise Guidelines. Chapter three, The effects of vessels on group cohesion and behavior of southern resident killer whales (Orcinus orca), discusses research investigating changes in killer whale group cohesion in response to vessel density, distance and mode of operation. Future cetacean studies would benefit from using the equipment and methods presented here, especially in areas that are not conducive to land-based theodolite collected data.

Download or read book Puget Sound Whales for Sale written by Sandra Pollard and published by Arcadia Publishing. This book was released on 2014-06-24 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: A look at the history of the commercial capturing of orcas in Washington’s Puget Sound, the whales taken, and the efforts to save them. In November, 2005, Washington’s iconic killer whales, known as Southern Resident orcas, were placed on the endangered species list. It was a victory long overdue for a fragile population of fewer than one hundred whales. Author and certified marine naturalist Sandra Pollard traces the story and destinies of the many Southern Resident orcas captured for commercial purposes in or near the Puget Sound between 1964 and 1976. During this time, these highly intelligent members of the dolphin family lost nearly one-third of their population. Drawing on original archive material, this important volume outlines the history of orca captivity while also recounting the harrowing struggle—and ultimate triumph—for the Puget Sound orcas’ freedom. “Making liberal use of interviews, correspondence and newspaper accounts, as well as less intensive use of legislative, governmental, and nonprofit records, Pollard constructs an easily digestible narrative for lay individuals curious about the hunting of Puget Sound’s Northern and Southern Resident killer whale groups between 1965 and 1976. Puget Sound Whales for Sale significantly succeeds the former (Blackfish) in breadth and depth.” —Pacific Northwest Quarterly

Download or read book Recovery Plan for Southern Resident Killer Whales Orcinus Orca written by and published by . This book was released on 2008 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This plan identifies a range of actions that will contribute to recovery of Southern Resident killer whales. Many of these actions will have a direct effect on killer whale habitat, but they will also help restore and improve a range of habitats, species and ecosystem processes. Although the recovery plan is focused on Southern Residents, the proposed actions will benefit many native species and natural communities. The plan refers to significant efforts on local, state and regional levels to address recovery of other species (particularly salmon), clean up of Puget Sound and management of local resources. Salmon recovery programs throughout Washington, Oregon and California as well as in Canada identify goals that will benefit the entire ecosystem. The Puget Sound Partnership provides a comprehensive approach to cleaning up inland waters of Puget Sound. There are numerous local efforts that are also focused on improving the health of the ecosystem such as the Marine Stewardship Area established in San Juan County. Over time, each of these programs should improve the overall health and biodiversity of the ecosystem. This plan provides background information on Southern Resident killer whale life history and status, and existing protective measures. Recovery goals and criteria are provided along with recovery actions, research and monitoring tasks in a narrative outline. Priorities and costs for the measures are provided in an implementation table"--Introduction.

Book excerpt: The Law Library presents the complete text of the Endangered or Threatened Species - Southern Resident Killer Whale Distinct Population Segment - Listing Amendments (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 On January 25, 2013, we, NMFS, received a petition submitted by the People for the Ethical Treatment of Animals Foundation to remove the exclusion of captive animals from the endangered species listing of Southern Resident killer whale DPS, as well as, recognize the captive killer whale (Orcinus orca) "Lolita" as a protected member of the endangered Southern Resident killer whale Distinct Population Segment (DPS). We completed a status review and published a proposed rule, and we are now amending the regulatory language of the Endangered Species Act (ESA) listing of the DPS by removing the exclusion for captive members of the population. We have further determined that Lolita, a female killer whale captured from the Southern Resident killer whale population in 1970 who resides at the Miami Seaquarium in Miami, Florida, is not excluded from the Southern Resident killer whale DPS due to her captive status. This ebook contains: - The complete text of the Endangered or Threatened Species - Southern Resident Killer Whale Distinct Population Segment - Listing Amendments (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition) - A dynamic table of content linking to each section - A table of contents in introduction presenting a general overview of the structure
